What is an audio codec used for?
An audio codec converts analog audio signals into digital signals for transmission or encodes them for storage. A receiving device converts the digital signals back to analog form using an audio decoder for playback. An example of this are the codecs used in the sound cards of personal computers.
What is the best audio codec?

What are different audio codecs?
There are three categories of codec: uncompressed, lossy, and lossless.
- Uncompressed: Uncompressed audio files encode the full audio input signal into a digital format capable of storing the full load of the incoming data.
- Lossy: Lossy files are encoded differently than uncompressed.
What are examples of codecs?
Codecs are compression technologies and have two components, an encoder to compress the files, and a decoder to decompress. There are codecs for data (PKZIP), still images (JPEG, GIF, PNG), audio (MP3, AAC) and video (Cinepak, MPEG-2, H. 264, VP8). There are two kinds of codecs; lossless, and lossy.

Do audio codecs matter?
A codec is a device or program that compresses data for transmission and decompresses the received data. In the case of audio, codecs affect your listening experience, whether you’re using headphones, earbuds or one of the best Bluetooth speakers.
Is AAC a codec?

What is codec and what does it do?
A codec is either a hardware device or a software-based process that compresses and decompresses large amounts of data used in voice over IP, video conferencing and streaming media. A codec takes data in one form, encodes it into another form and decodes it at the egress point in the communications session.
